    algae on your waterfall is good it cleans the water .But us ponders love our rocks .I use peroxide .I turn off my pump and make sure the aerator is going .I spray the rocks with peroxide and use a toilet bowl brush to take off the heavy stuff .I then spray again and wait 15 minutes and then turn everything back on .It helps to do it when it is sunny out .It kills it faster

    Thanks for that Sissy, I have a pond less waterfall, the algae problem is on the gravel under the stream and looks unsightly, I don't mind it on the rock, it will always jet wash off :)

    since it is pondless you could just pour a couple of bottles in there every couple of months .It should keep it clean .I have seen them also use solar salt for water softeners and pool chemicals

    yep it does not stay in the water .But you would not want the pets drinking it right after you treat it .I use it in my bird bath along with solar salt to keep water fresh and clean 2 tablespoons of each .It is good to take a bath in with baking soda and epsom salts it balances your ph calm sore muscles and makes skin soft

    Peroxide has been safe for the fish I have in my pond... Sissy got me using the peroxide as well because I have horrible amounts of string algae that I can't seem to tame. I've seen the fish swim through an area I just poured the peroxide and it never seems to affect them. Also keep in mind that the peroxide dissipates after a few minutes, so by the time you turn your pump back on it will be completely inert. Another thing to consider... you use peroxide to clean your mouth after dental surgery. Its safe for us to swallow it, so it's likely also safe for pets. I keep my dogs out of the water while I'm doing a treatment, but once the pumps are back on they start drinking the water again without any ill effects.

    We buy sodium percarbonate to treat our waterfall and rocks. It's a granular product that breaks down into hydrogen peroxide and soda ash when it comes in contact with the water. It's sold as a pond product under various names (GreenClean, Ecoblast, etc) for about 10-15 times the cost. It's safe to use, it's simple, and it's effective. Just shut down the waterfall (aerators on), sprinkle it wherever you see algae, wait 20 minutes and turn the water back on. No more algae.

    Not that I am aware of. I've never seen anything that would indicate it's not fish safe. More importantly we have used it for years without any problems for fish or plants. And you can purchase it under many names as a pond product.

    I just buy 2L of the drug store 3% peroxide ( 4 x 500mL ) I pour it into my waterfall feeder source on a sunny day. I don't scrub as it just seems to die back and disappear over a few days. Seems to last me about 4 weeks before I need to treat again. Cost for 2L is less than $10.00, and hydrogen peroxide is safe as it's just H2O2 (hyper oxygenated water more or less) The higher percentages of peroxide (35% Food grade) is corrosive and is used as a food services sanitizer. At 3% it's not corrosive and is fish safe and pet safe in the diluted amount that would be in your water. Heck, people use 3% as a mouthwash and teeth whitener. Bye-bye string algae. After 4 years, my fish never seem to mind it at all, nor did my tadpoles.

    I buy the gallon jugs from a supply house here and if you buy a whole case of 6% you can get it for 10 dollars with tax .I dilute it before I use it .I used to buy it at walmart 88 cents and then from a friend who works at a nursing home but she forgot to order it for me this last time.I keep it stored in the cool basement because heat can affect it .Brown bottles are used because light breaks it down .The nursing home use's it to clean everything with instead of bleach .

    I also use the stuff from walmart... 88 cents for a 1 liter bottle. I use two bottles at a time, but last time I forgot about shutting down the pumps. I may have to hit it again on Thursday.

    My pond is about 3000 gallons and I have a real algae problem. Peroxide sounds like a promising algaecide. I'm wondering how much of it you use and how often you all use it though.

    Just watch your plants because it can kill them if you use to much to often or remove the in pond plants .I use about 1 of those bottles 1 time a month but mix it with water just before I add it since mine is stronger and my pond is about 4000 gallons .Try to not pour it in 1 area unless that is the area you are having problems with .I spray my waterfall rocks with it full strength .Not sure how it would effect a U.V . I just bought 2 of them for fish I was taking care and the people paid for them and then they bought 2 -36 watt ones for there new pond and told me to keep the other ones for helping them out .I wonder if it would effect the quartz sleeve any .I am using 1 of them in a 350 gallon stock tank and did that clear up fast .Not sure if that was the peroxide I added before that or the U.V..Then thought will peroxide effect U.V. ,but it is still working .Makes me wonder though .

    I generally use a whole bottle poured across my waterfall because that's where the algae grows the worst. The bottles I get have a hole in the lid so you can squirt it on an area. I use this to squirt directly into the middle of the worst patches around my pond. After about 5 minutes you will see the algae bubbling and clumps floating to the surface. I don't think I would treat more often than once every week or two if you have fish, and I don't use it near the invertebrates (like snails).
